Machac, 23, made the brighter start to the match, imposing himself with a flurry of crunching forehands and taking Draper to deuce in the Briton’s opening service game.<\/p>\n
But Draper withstood the early barrage, settled in with three aces in his next service game and soon began to take control.<\/p>\n
He was gifted the first break when Machac put a routine overhead into the net and then went long, but took full advantage, hammering a scorching backhand down the line to bring up two set points before converting a third.<\/p>\n
After showing his power from the baseline in the first, Draper showed his deft touch to start the second with a pair of fine drop shots.<\/p>\n
But while there was a swagger to an increasingly confident Draper, his opponent was growing ever more frustrated and heated discussions with coach Daniel Vacek between – and during – games became the norm.<\/p>\n
Double faults were becoming an issue for the Czech world number 39 and two in a game enabled his opponent to break at the first time of asking in the second set.<\/p>\n
Having got the advantage, Draper was ruthless as he moved serenely around the court, coolly staving off a break-back point before earning his second break to go up 5-1.<\/p>\n
Two eye-catching winners helped him serve it out and the prospect of a Machac comeback looked unlikely when the Briton broke in the first game of the third set.<\/p>\n
Of the six break points Draper faced five came in his final two service games as Machac – by this stage two breaks down – tried to delay the inevitable but again the British number one kept his cool.<\/p>\n
With a quarter-final place confirmed, another win would see Draper become the first Briton to make the men’s semi-finals in New York since Murray claimed his first Slam in 2012.<\/p>\n<\/div>\n
